ALARM CLOCK .AND WATCH.

Specification of Letters Patent.

Patented Dec. 12, 1911.

Application led September 30, 1905, Serial No. 280,808. RenewedFebruaryll, 1911. Serial No. 608,396.

To all whom it may concern:

Be it known that I, CHARLES Louis FAivim, watchmanufacturer, citizen ofSwitzerland, residing at Le Locle, Canton of Neuchatel, Switzerland,have invented new and useful Improvements in Alarm Clocks and Vatches,of which the following is a specification.

This invention relates to alarm mechanism for application to clocks orwatches and consists in cert-ain devices for locking and releasing theusual vibratory hammer and also manually operable means for effectingthe release of the hammer', to operate the alarm, at a predeterminedtime.

The invention will be more fully described in connection with theaccompanying drawing and will be more particularly pointed out andascertained in and by the appended claims.

In the drawing Figure 1 is a view of the manually operable means forsetting the alarm. Fig. 2, is a reverse view. Fig. 3, is an enlargedsectional View on line A-B of Fig. 2. Fig. 4, is a sectional view online C-D of Fig. 3.

Like characters of reference designate similar parts throughout thedifferent figures of the drawing.

As shown in the drawing A portion of the time train is indicated in Fig.2 by wheels l, 2, 3, t and 5, said wheel 5 meshing with a barrel pinion6 actuated by a spring 7. IVheel Z, Figs. l and 3, is fast to the arborof the hour hand, (not shown), and meshes with and is positively drivenby wheel o, of equal diameter, which is mounted on arbor 7c. A wheel c,equal in diameter to wheel o, is also mounted on arbor la and is heldthereby in frictional contact with wheel o to afford relative adjustmentof the former with respect to t-he latter.

An improved adjusting or setting means is provided for adjusting thesetting wheel 7c which consists of the following construction. Aswinging or adjusting member s, preferably in the form of the bell cranklever, is pivotally mounted at t to the pillar plate b or otherstationary part and carries at r a wheel p adapted to mesh with thesetting wheel c and a wheel Q, adapted to rotate with the wheel j) andin mesh with a manually operable wheel o rotatably mounted at t. Saidmember s is provided with an extension u, adapted to normally projectthrough the case, diagrammatically indicated by line e. As will be seenby reference to Fig. l, the manually operable wheel o also projectingbeyond the case. A spring a engages the swinging member s and serves tonormally hold the wheel p out of mesh with wheel 7c. An index 7a2secured to t-he wheel 7c rotates abreast of a graduated portion 7c3visible to the operator, so as to indicate the position to which thewheel 7c has been set.

When it is desired to set the alarm mechanism the operator pressesinwardly on the extension u against the action spring fr while forcingthe wheel p into mesh with the wheel 7c. Wheel c is then set by rotatingthe manually operable wheel o. A striker or hammer i is pivotallymounted at t" in a bridge 2 and in the pillar plate and is operated froma spring barrel 7 through the medium of wheels, 4, 5, 6 and a ratchetwheel 3 and escapement pawl 8 which latter are mounted at z". A gong ais secured to the pillar plate Z) by the mounting 'n' in strikingproximity to the hammer Said hammer z' is provided with a projection L,Fig. 4, adapted to be engaged byapin f provided with a knife edge f andheld thereby in a retracted position. The pin is mounted in one end ofthe lever c which is secured at its opposite end to a spindle or arboro. A bridge a mounted on pillar plate supports the lever c and forms abearing for the arbor o. Said arbor c extends through the pillar plateZ) and carries on its opposite end a hand or index d. Said index dextends from the arbor c toward the wheel 7c and into the plane oftravel of a lug m mounted on said wheel. The disposition of the partsjust described is such that when the lug mengages the index l the latterserves through the arbor c and lever e to throw the pin f out ofengagement with the project-ion 7L releasing the hammer z' andpermitting the same to operate under the action of the independentlydriven alarm train hereinbefore described.

When the striker is engaged by the pin f and held in a retractedposit-ion it is desirable to provide means serving to hold the pin f inenga-gement with the shoulder h and it is necessary that said meanspermit of disengagement of the pin f from the projection h when the lugm engages the index (Z and to this end said means is designed toyieldingly engage the lever c or other suitable part connected with thepin f. As

shown a spring is provided having forked arms g which engage the lever eat opposite sides. Said arms g terminate in a base g rigidly secured tothe bridge a. In assembling the parts the base g is mounted upon thebridge a in a manner to cause the arms g to normally hold the pin inengaging proximity to the projection 7L as clearly shoivn in Fig. 2.

l claim l. A device of the class described comprising in combination agong, a striker therefor, a. pivotally mounted lever for holding saidstriker in a retracted position, a spring yoke engaging said lever onopposite sides to hold it in locking relation with said striker, and africtionally act-ing gear train for displacing said lever.

2. A device of the class described comprising in combination a gong, astriker therefor., a pivotally mounted lever for holding said striker ina retracted position, a spring yoke engaging said lever on oppositesides to hold it in locking relation with said striker, a positivelydriven pinion, and an adjustable pinion frictionally driven by saidfirst-mentioned pinion and cooperating with said lever to release saidstriker.

A device of the class described comprising in combination a gono, astriker therefor having a lug IL provided With a knife edge, a pivotallymounted lever provided ivith a pin having a knife edge engaging saidlug, a spring yoke engagingsaid lever on opposite sides to hold it inlocking relation ivith the striker, a spindle for said lever, a hand orpointer for said spindle, an adjustable pinion provided rvith a lugadapted to engage said hand, and a positively driven pinion frictionallydriving said adjustable pinion.

4. A device of the class described coinprising in combination a gong, astriker therefor, pivotally mounted lever for holding said striker in aretracted position, a spring yoke engaging said lever on opposite sidesto hold it in locking relation ivith said striker', a frictionallyacting gear train for displacing said lever, and setting mechanism forsaid frictionally acting gear train.

'3. ik device of the class described comprising in combination a gong,a. striker striker, a positively driven pinion, and an adjustable pinionfrictionally driven by said hist-mentioned pinion and cooperating withsaid lever to release said striker, and setting mechanism for saidadjustable pinion.

C. A device of the class described comprising in combination a gong, astriker therefor, a pivotally mounted lever provided ivith a pin havinga knife edge for holfling said striker in a retracted position, a springyoke engaging said lever on opposite sides to hold said pin in lockingrelation with said striker, an index or hand associated ivith saidlever, a positively driven pinion, an adjustable pinion frictionallydriven by first mentioned pinion and provided vvith a lug adapted toengage said index, setting mechanism for actuating said adjustablepinion and comprising a swinging lever provided with an extensionadapted to project through the case, a Wheel for sai 'l lever adapted tomesh vfith said adjustable pinion, a second Wheel rotating 'vvith saidirst Wheel, a third Wheel meshed with said second Wheel adapted toproject through. the Watch case, and a spring engaging said lever andnormally holding it in an inoperative position.

A device of the class described comprising in combination, a gong, astriker therefor, means for holding said striker in a retractedposition, oppositely acting yielding elements engaging said means tohold the same in locking relation ivith the striker, and mechanism fordisplacing said means.

S. A device of the class described comprising in combination, a timetrain, an aetuatmg member driven thereby, an alarm tain, a soundingelement, a striking device operating thereon and driven from said alarmtrain, a movable member holding said striking device in a non-operatingposition, oppositely acting yielding elements engaging said movablemember to hold the saine in locking relation to the striker, and meansassociated with said movable member and normally out of engagement withsaid actuating member and adapted to be actuated thereby to release saidstriking device.

in testimony whereof l have signed my name to this specification in thepresence of tivo subscribing Witnesses.
